4 DESCRIPTION OF THE APPLIANCE
4.1 Characteristics
ALU HE
aluminium boilers generate heat through condensation
and are designed to heat rooms and produce domestic hot water,
if the system contains a storage tank. They are composed of:
– an aluminium body, with low water content and high exchange
surface, to maximise energy efficiency and heat yields
– a total pre-mix microflame burner in stainless steel that
allows high modulation ratios, combustion stability and low
emissions of pollutants (Class NOx = 6), to be achieved
– a variable speed fan required for modulation and air/gas
mixing
– a combustion circuit which can be "Type C" (sealed) or
"Type B" (open) with respect to the place where the boiler is
installed, depending on the configuration of the combustion
air inlet adopted during installation
– a control panel which. if equipped with an external sensor,
allows the delivery temperature to be adjusted according to
the outdoor temperature (sliding temperature operation).
The boiler therefore provides only the heat the User actually
needs, avoiding energy being wasted and the associated
costs. If there are malfunctions or faults, the specific error
codes are displayed, which simplifies the work of Technical
Service.
During planning solutions have been adopted to:
– constantly achieve the best air/gas mixture
– reduce heat dispersion
– reduce noise.
Sime ALU HE
boilers can be installed as single units or in a
cascade composed of between two and eight appliances with
the same heating output.
When boilers are connected in a cascade, they communicate
ONLY with the master boiler, treating the cascade as a single
heat generator where:
Cascade output = Boiler output x no. of boilers installed
Sime ALU HE
boilers can be connected to 0-10 V DC controls, to an
auxiliary sensor and to the
Sime Home
or
Sime Home Plus
remote
controls. They can manage direct systems or direct systems and
two mixed systems (or two groups of mixed systems connected
in parallel), if the optional kits "mix 1 kit-code 8092275" and "mix
2 kit-code 8092276" are installed. A solar system can also be
installed using the “solar kit-code 8092277” and the “MODBUS
interface code 8092278” to communicate via MODBUS with
remote devices. All kits are optional accessories to be ordered
separately. After each stoppage, whether automatic or manual,
post-ventilation and post-circulation are performed. The
system should include an INAIL safety device 8101595, which
is mandatory for ITALY ONLY, and a plate heat exchanger or
hydraulic separator, depending on the system characteristics.
Sime ALU HE
boilers also have the following functions:
– anti-freeze function, which is activated automatically if the
temperature of the water inside the boiler falls below the
value set under “PAR 35” and if the outdoor temperature falls
below the value set under “PAR 36”
– antiblocking function for the pump and any diverter valve,
which is activated automatically every 24 hours if there have
been no requests for heat
– the chimney sweep function lasts 15 minutes and makes the
job of the qualified technician easier when measuring the
parameters and combustion efficiency
– anti-legionella function when a storage tank is used
– automatic adjustment of the ignition output and minimum
and maximum heating output. The outputs are managed
automatically by the electronic circuit board to ensure
maximum system usage flexibility
– dispersal function, so that if the delivery probe detects a
temperature of 90°C, the fan runs until it falls to 89°C
– screed drying function, to keep the floor at a pre-set
temperature profile with the help of the mixer valve
– "External sensor value correction" function.
4.1.1 Operation
When the general switch is activated the boiler is powered
with electricity. The blue bar (4) on the control panel lights
up. The symbols, "- -" message and the system pressure are
shown correctly on the screen. To turn the boiler on or off press
button T then button V to select "WINTER mode" or button
U to select "SUMMER mode". The value of the delivery sensor
detected at that moment appears on the display.

CAUTION
When the display is not backlit (off), the first press on
each function button serves to backlight it (turn it on);
the second press to carry out the command.
When heat is requested from the systems or the storage tank,
if there is one, the control panel automatically carries out the
functional checks, and electrically powers the gas valve and
ignition transformer to turn on the flame. This is how automatic
operation of the boiler begins. When the request for heat is
fulfilled the flame goes out, but the fan and the circulation pump
remain in operation to carry out post-ventilation and post-
circulation at the end of which they stop and wait for the next
request for heat.
